Derek, Ok, the timer is something I had just tried before I checked here, & did discover that it wouldn't run from a button press, & then I saw some places in Win32Lib that seemed to exclude onMouse from buttons (anything but windows?), so I see what you're saying. My only question is, would the change you indicated be included in the next version of Win32Lib, so my code could work for anyone ?
